Abstract

Objective The use of self-expanding stent grafts for treatment of popliteal artery aneurysms (PAA) is a matter of debate, although several studies have shown similar results compared with open surgery. In recent years, a new generation stent graft, with heparin-bonding technology, became available. The aim of this study is to present the results of endovascular PAA repair with heparin-bonded stent grafts. Methods Data on all patients with PAA treated with a heparin-bonded polytetrafluoroethylene (ePTFE) stent graft between April 2009 and March 2014 were gathered in a database and retrospectively analyzed. Data were collected from four participating hospitals. Standard follow-up consisted of clinical assessment, and duplex ultrasound at 6 weeks, 6 months, 12 months, and annually thereafter. The primary endpoint of the study was primary patency. Secondary endpoints were primary-assisted and secondary patency and limb salvage rate. Results A total of 72 PAA was treated in 70 patients. Mean age was 71.2 ± 8.5 years and 93% were male (n = 65). The majority of PAA were asymptomatic (78%). Sixteen cases (22%) had a symptomatic PAA, of which seven (44%) presented with acute ischemia. Early postoperative complications occurred in two patients (3%). Median follow-up was 13 months (range 0-63 months). Primary patency rate at 1 year was 83% and after 3 years 69%; primary assisted patency rate was 87% at 1 year and 74% after 3 years. Secondary patency rate was 88% and 76% at 1 and 3 years, respectively. There were no amputations during follow-up. Conclusion Endovascular treatment of PAA with heparin-bonded stent grafts is a safe treatment option with good early and mid-term patency rates comparable with open repair using the great saphenous vein.
